    Physicists are mostly unconvinced by Microsoft’s new topological quantum chip

    ANAHEIM, CALIF. — At the world’s largest gathering of physicists, a talk about Microsoft’s claimed new type of quantum computing chip was perhaps the main attraction. 

    Microsoft’s February announcement of a chip containing the first topological quantum bits, or qubits, has ignited heated blowback in the physics community. The discovery was announced by press release, without publicly shared data backing it up. A concurrent paper in Nature fell short of demonstrating a topological qubit. Microsoft researcher Chetan Nayak, a coauthor on that paper, promised to provide solid evidence during his March 18 talk at the American Physical Society’s Global Physics Summit. More

    A quantum computing milestone is immediately challenged by a supercomputer

    The tug-of-war between quantum computers and classical computers is intensifying.

    In just minutes, a special quantum processor, called a quantum annealing processor, solved a complex real-world problem that a classical supercomputer would take millions of years to complete, researchers claim March 12 in Science. And that supercomputer, the team reports, would consume more energy to run the whole computation than the entire globe uses in a year. However, another group of researchers claims to have already found a way for a classical supercomputer to solve a subset of the same problem in just over two hours. More

    Quantum mechanics was born 100 years ago. Physicists are celebrating

    A century ago, science went quantum. To celebrate, physicists are throwing a global, year-long party.

    In 1925, quantum mechanics, the scientific theory that describes the unintuitive rules of physics on very small scales, began to crystallize in the minds of physicists. Beginning in that year, a series of monumental papers laid out the theory’s framework. Quantum physics has since permeated a wide range of scientific disciplines — explaining the periodic table, the lives and deaths of stars and more — and enabled technologies from the laser to the smartphone.
